E-learning courses are designed based on “One Content-Fits All”, this is not true, because there are individual differences between students in abilities, cultures, backgrounds, preferences, and learning styles. The key issues characteristic of populations of online learners are their diversity. This diversity requires the presentation of different information to different learners in a different format. That is why it is very important to develop adaptive educational systems which consider various aspects of individual students in order to make the learning process as effective, efficient, and motivating as To attempt to ensure the success of these types of learners, online instruction must adapt strategies that acknowledge the individual characteristics of these learners.
